Results of the generalised additive mixed models (GAMMs) predicting the effect of degree of mismatch or degree of relative mismatch on handling time or sugar extraction rate, fitting a Gaussian distribution. Handling time and sugar extraction rate were log10 transformed. Sugar content was included as an additional explanatory variable in de models predicting handling time. In all models, insect species was included as a random factor
